HISTORY of the LZMA SDK

23.01 2023-06-20
|
||||
-------------------------
|
||||
- 7-Zip now can use new ARM64 filter for compression to 7z and xz archives.
|
||||
ARM64 filter can increase compression ratio for data containing executable
|
||||
files compiled for ARM64 (AArch64) architecture.
|
||||
Also 7-Zip now parses executable files (that have exe and dll filename extensions)
|
||||
before compressing, and it selects appropriate filter for each parsed file:
|
||||
- BCJ or BCJ2 filter for x86 executable files,
|
||||
- ARM64 filter for ARM64 executable files.
|
||||
Previous versions by default used x86 filter BCJ or BCJ2 for all exe/dll files.
|
||||
- Default section size for BCJ2 filter was changed from 64 MiB to 240 MiB.
|
||||
It can increase compression ratio for executable files larger than 64 MiB.
|
||||
- Some optimizations in filters code: BCJ, BCJ2, Swap* and opthers.
|
||||
- If 7-Zip uses BCJ2 filter for big datasets compressing, it can use additional temp
|
||||
files in system's TEMP folder. 7-Zip uses temp file for additional compressed
|
||||
data stream, if size of such compressed stream is larger than predefined limit:
|
||||
16 MiB in 32-bit version, 4 GiB in 64-bit version.
|
||||
- When new 7-Zip creates multivolume archive, 7-Zip keeps in open state
|
||||
only volumes that still can be changed. Previous versions kept all volumes
|
||||
in open state until the end of the archive creation.
|
||||
- 7-Zip for Linux and macOS now can reduce the number of simultaneously open files,
|
||||
when 7-Zip opens, extracts or creates multivolume archive. It allows to avoid
|
||||
the failures for cases with big number of volumes, bacause there is a limitation
|
||||
for number of open files allowed for a single program in Linux and macOS.
|
||||
- Some bugs were fixed.
|
||||
- Source code changes:
|
||||
- All external macros for compiling C/C++ code of 7-Zip now have Z7_ prefix.
|
||||
- 7-Zip COM interfaces now use new macros that allow to declare and implement COM interface.
|
||||
- The code has been modified to compile with the maximum diagnostic warning level:
|
||||
-Wall in MSVC and -Weverything in CLANG.
|
||||
And some warning types are disabled in 2 files:
|
||||
- C/Compiler.h for C/C++ code warnings.
|
||||
- CPP/Common/Common.h for C++ code warnings.
|
||||
- Linux/macOS versions of 7-Zip: IUnknown interface in new code doesn't use
|
||||
virtual destructor that was used in previous 7-Zip and p7zip:
|
||||
// virtual ~IUnknown() {}
|
||||
So 7-Zip's dynamically linked shared libraries (codecs) are not compatible
|
||||
between new 7-Zip for Linux/macOS and old 7-Zip (and p7zip).

-------------------------
|
||||
- New switches: -spm and -im!{file_path} to exclude directories from processing
